2 Claims.

This invention relates to bricklayers 'equipment and it has particular reference to a line holder, generally known to the trade as a bricklayers line trig.

The principal object of the invention is to provide a device for firmly and accurately holding a line in relation to a brick or tile structure to predetermine the position of succeeding courses, its construction being such that it may be conveniently carried in the pocket when not in use and quickly attached to and detached from a trig brick in mounting a line.

Another object of the invention is to provide for length adjustment of the device so that the latter may be adapted to masonry units of different lengthsI and widths.

With the foregoing objects as paramount, the invention has particular reference to its salient features of construction and arrangement of parts which will become manifest as the description proceeds, taken in connection with the accompanying drawing, wherein:

Figure 1 is a side elevational View of a line holding device constructed according to the invention.

Figure 2 is a view similar to Figure 1 showing the invention extended.

Figure 3 is a fragmentary brick wall section showing the relationship of the invention and line therewith, and

Figure 4 is a plan view reduced in size, showing the invention adjusted to conform to a building tile.

Continuing with a more detailed description of the drawing, the preferred form of the invention is comprised primarily of a length of strap metal I in which there is provided a longitudinal slot a (Figure 4) terminating short of the ends thereof. A lever 2 under tension of a spring 3 is pivoted at b to a frame 4, adjustably mounted on the strap I for the purpose hereafter referred to. The spring 3 is lconnected at 5 to a point on the lever 2 immediately below the pivot point b.

and to the downwardly bent leg 4a of the frame. The upper end of leg 4a is bent downwardly upon itself and extends rearwardly to provide the mounting for lever 2 at b, thereby affording through the medium of the upper end of leg 4Z and the lever above its pivot point, nger grips by which the lower extremity of the lever 2 is moved, against the resistance of spring 3 to attach and detach the device with respect to a trig brick 5a (Figure 3). Y

The frame 4 is connected to the strap I through the medium of a wing nut 6, threaded onto a stove bolt 'I which passes through an aperture in the foot Iia bent outward from the leg 4a, thence through the slot a of the strap, terminating in a beveled head la, corresponding with the beveled edges (not shown), of the slot a on the underside of the strap.

'Ihe free end of strap I has a right angular bend or lip 8 to extend downwardly in parallel relation to the lower extremity of lever 2 and engages the side of a masonry unit opposite that of the lever 2 to clamp th'e device thereon under the tension of spring 3.

In operation, the upper end of lever '2 is urged toward the upright portion 4a of the frame to expand spring 3 and the device is placed on a masonry unit with the lip 8 and lever 2 overreaching the opposite edges of the unit. When the lever is released, the spring will function to retain the device rmly on the brick or tile as the case may be. 'I'he line 9 is placed in the recess IU in the manner shown in Figures 3 and 4, before the device is mounted.

It is apparent from the foregoing that as many line holders as necessary may be used, depending on the length of the line or weather conditions, such as high winds, likely to whip' the line and cause disalignment thereof. Moreover, it is likewise apparent that other resilient means may be substituted for the spring 3 with equal results.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of thevinvention.

What is claimed is:

1. A bricklayers line holder comprising a longitudinally slotted strap having a brick engaging lip on one end thereof provided with a line receiving recess therein, a frame having a leg at right angles to said strap with a portion bent into parallel relation to said strap for longitudinal sliding movement thereon, a lever pivoted intermediate its ends to said frame, a spring connected at one end to said leg and at the other to said lever below its pivot point to constrain said lever to move under tension toward said lip to engage a brick on the side thereof opposite said lipI and means passing through the bent portion of said leg and the slot of said strap forl securing said strap and frame in' relatively adjusted positions.

2. A bricklayers line holder including a longitudinally slotted strap forming a base and a its pivot point for yieldingly urging the lower end of said lever against said masonry unit on.

the side thereof opposite said lip and means connecting the bent portion of said leg with the slot of said strap to secure said strap and frame in relatively adjusted positions.
